Abstract

A cover for a percutaneous connector extending through the skin of a patient. The cover includes a structure having an inner side and an outer side. A first separable connector is mounted to the structure and disposed entirely within the structure, the first separable connector being configured to detachably engage and electrically connect with the percutaneous connector. A second separable connector is mounted to the structure and electrically connected to the first separable connector, the second separable connector being exposed at the outer side of the structure and being configured to detachably engage and electrically connect with an external device. The inner side of the structure defines a skin-engaging surface at least partially surrounding the first separable connector and the percutaneous connector, when the first separable connector is engaged with the percutaneous connector.

Claims

1. A cover for a percutaneous connector extending through the skin of a patient comprising:

an enclosure having an inner side and an outer side and defining a depression;

a first separable connector mounted to the enclosure and disposed entirely within the enclosure, the first separable connector being configured to detachably engage and electrically connect with the percutaneous connector, the enclosure being configured to isolate a distal end of the percutaneous connector from an exterior of the enclosure;

a second separable connector mounted to the enclosure and disposed within the depression, the second separable connector being electrically connected to the first separable connector, the second separable connector being exposed at the outer side of the enclosure and being configured to detachably engage and electrically connect with an external device, the second separable connector being spaced apart from the first connector by a cable; and

the inner side of the enclosure defining a skin-engaging surface at least partially surrounding the first separable connector and the percutaneous connector, when the first separable connector is engaged with the percutaneous connector.

2. The cover of claim 1, wherein the skin-engaging surface extends entirely around the first separable connector.

3. The cover of claim 1, further comprising an adhesive on the skin-engaging surface.

4. The cover of claim 1, wherein the enclosure includes a housing and a flexible base extending beyond a periphery of the housing, the flexible base defining at least a portion of the skin-engaging surface.

5. The cover of claim 4, wherein the base is integral with the housing.

6. The cover of claim 4, wherein the second separable connector is disposed in a second housing and connected to the first separable connector by an electrical conduit, the second separable connector being accessible to connect with an external device and manipulation of the second separable connector does not interfere with the connection between the first separable connector and the percutaneous connector when the cover is disposed over the first separable connector and the first separable connector is engage with the percutaneous connector.

7. The cover of claim 1, further comprising a closure configured to releasably engage at least one from the group consisting of the enclosure and the second separable connector, the closure being configured to cover the second separable connector when the external device connection is absent.

8. The cover of claim 1, further comprising an alarm mounted to the enclosure and electrically connected to at least one from the group consisting of the first separable connection and the second separable connector, the alarm being configured to emit an alarm signal responsive to an electrical condition prevailing at the at least one from the group consisting of the first separable connection and the second separable connector.

9. The cover of claim 8, wherein the alarm signal includes at least one from the group consisting of an audio, tactile, and visual alarm.

10. A method of providing a connection between an external device and an internal device implanted in a patient and electrically connected through a percutaneous connection element across a skin surface of the patient, the method comprising:

coupling a first separable connector to the to the percutaneous connection element;

securing the first separable connector to the skin surface independent of the engagement between the first separable connector and the percutaneous connection element, the first separable connector being spaced apart and electrically connected to a second separable connector exposed outside of the patient, the first connector being coupled to a cover, and the second connector being disposed within a depression defined by the cover, the cover being configured to enclose and isolate a distal end of the percutaneous connection element from an external environment; and

connecting the external device to the second separable connector.

11. The method of claim 10, further comprising detaching the external device from the second separable connector.

12. The method of claim 11, further comprising removing the first and second separable connectors.

13. The method of claim 10, wherein securing the first separable connector includes applying an adhesive-bearing element to the skin of the patient, and wherein the adhesive-bearing element holds the first separable connector in place.

14. The method of claim 13, wherein the percutaneous connection element is a percutaneous connector extending through the skin, and wherein application of the adhesive-bearing element covers the percutaneous connector and protects the percutaneous connector from microbes.

15. The method of claim 13, wherein applying the adhesive-bearing element includes applying the cover including the first separable connector and the adhesive-bearing element.

16. The method of claim 15, further comprising operating an alarm circuit mounted to the cover and electrically connected to at least one of from the group consisting of the first separable connector and the second separable connector, the alarm circuit being configured to detect an electrical condition representing a condition of the internal device and emit an alarm signal responsive to such condition.

17. The method of claim 10, wherein the percutaneous connection element is a percutaneous cable extending through the skin surface of the patient.

18. The method of claim 17, wherein the first separable connector is secured to the skin remote from a skin breach location where the percutaneous cable extends through the skin.

19. A cover for a percutaneous connector extending through the skin of a patient comprising:

a housing defining a substantially dome shape and a base surrounding the housing and extending beyond the periphery of the housing, the housing isolating a distal end of the percutaneous connector from an external environment;

a first separable connector mounted to the structure and disposed entirely within the housing, the first separable connector being configured to detachably engage and electrically connect with the percutaneous connector; and

a second separable connector entirely mounted within a depression defined by the dome and electrically connected to and spaced part from the first separable connector, the second separable connector being exposed at the outer side of the dome and being configured to detachably engage and electrically connect with an external device,

the inner side of the base defining a skin-engaging surface surrounding and enclosing the first separable connector and the percutaneous connector when the first separable connector is engaged with the percutaneous connector, the inner side including an adhesive on the skin-engaging surface.
